This is all based on appearance of the “rat poison” pills, but I looked it up and found that its appearance is like alphazolam, a drug used in the treatment for people who have BPD.
I don’t know what this means or if its just a coincidence, but I just wanted to share my findings.
Update: I looked up side effects of this drug and:
“Common Side effects of Xanax (alprazolam) include drowsiness, dizziness, insomnia, memory problems, poor balance or coordination, slurred speech, trouble concentrating, and irritability.
Other, less common, side effects can include diarrhea, sweating, headache, nausea, blurred vision, and appetite changes.”
The side affects explain why Bum got sick.
Again, it might be another coincidence.
